RAZOR-BLADE nonnnn.

Application flled August 22, 1924. Serial No. 733,629.

To all *whom it may concern:

Be it known that 1, Don PARDEE Moon, a citizen of the United States, residing at Kokomo, in the county of Howard and State of Indiana, have invented certain new and useful Improvements in Razor-Blade Hold ers; and it do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in razor blade holders and has for an object to provide a holder for a blade useful in connection with stropping the blade or formin a knife for ripping seams, sharpening pencils, cutting leather and fur, stencil cutting, wood block carving, whittling, trimming wall paper, erasing ink from drawing paper, paring corns, scraping glass, etc.

Another object of the invention consists in providing an improved device of this character in which a magazine s provided for holdinga quantity of the razor blades and in which a novel and improved means is provided for clamping the blade in the holder.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views,

Figure 8 is a fragmentary section showing a detail.

- Referring more particularly to the drawings and for the present to Figures 1 to 3 inclusive, the device consists generally of two members having the substantially flat clamping jaws 9 and 10 perforated to renews the screw post 11 having the nut-12 threaded thereon for binding the clamp jaws upon the blade indicated at 13. The nut 12 is preferably a wing nut for facility in gripping and turning. The head of the screw post 11 is preferably square to engage a square opening in the jaw 10 to avoid rotation when turning the nut 12; or the head may be secured against rotation in any desired manner.

Back of the jaws the two members are cut away as indicated at 14 and 15, the removed portions being preferably on relatively reverse arcs of circles in order to admit the thumb and finger to accommodate the contour of these members. it neck 13 is left between the removed portions and just forwardly of the removed portions and 'preferably on the longitudinal centers of the members are perforations 1?. As shown in Figure 2 the planes of the clamps 9 and 10 are oif set toward one another inwardly of the planes of the remaining portions of the two members.

The outer portions 17 and 18 of the members are preferably longer than the clamps and constitute a handle for supporting the blade holder when in use. The handle members 1? and 18 are closed at their sides as in dicated at 19 and 20 in Figure 3 in order to provide a magazine for holding additional blades as shown, The members are secured together by a post or rivet 21 at a point preferably on the longitudinal centers of the members and outwardly of the convergent portions 22 and 23 thereof in order not to interfere with the resilient action of the memhere. These members are made of prefer ably some metal possessing sufiicient inherent resiliency to normally hold the clamp jaws 9 and 10 slightly apart and the resilient action is heightened by the convergent parts 22 and 23 in combination with the cut out side portions 14 and 15 and theperforations 17; The rivet 21 is placed also with reference to the length of the blades to be accommodated in the magazine. The end of the handle portion is open so that the blades may be inserted within this part and the rivet is spaced from this end portion slightly longer than the greatest length of the blade to be received in the magazine. Both ends of the device are preferably rounded as indicated in Figure 1 and the open end of the magazine may be kept closed by the arcuate cover 24 rovided with the indented end portions 25 ibr engaging the side walls of the magazine when the cover is closed in order to hold it in this position until actively and formbly dislodged. The cover 24 1s provided w1th the straps 26 extendin along the handle members 17 and 18 and t e inner ends of the straps are formed with inturned claws 27 fitting rather loosely withln perforations 28 in the handle members. The perforations 28 are arranged at the center of the circle on which the arc of the cover 24 is struck.

In the use of the device the blade may be clamped for instance as shown 1n Figure 1 between the jaws 9 and 10 and the handle gripped with the fingers engaged in the cut out portions 14 and 15. In th1s manner the device may be pushed across a glass surface for the purpose of removing paint and ink spots, putty and other form 11 substances. The blade may be turned at right angles to the position shown in Figure 1 and clamped in the holder to provide a pencil sharpener and knife of general utility. When the nut 12 is loosened the blades will tend to spring apart automatically releasing the blade so that its angular position may be changed or it may be removed or replaced by a fresh blade. The blades may be kept-in suitable quantities in the magazine from which they are withdrawn when their use is demanded.

Referring to Figures 4, 5 and 6 the device is generally similar except that the neck portions indicated at 30 between the blade clamps and handle portion are elongated and the cut out parts 31 and 32 are more rectangular with side walls slightly curved.

The handle parts indicated at 33 and 34 in this instance are not secured together by any such rivet as rivet 21 shown in Figure 2 but the two portions 33 and 34 meet on the line indicated at 35 in Figure 6, being held normally in this position by the sliding clasp 36 which is also preferably of spring metal and is held in place by reason of its own resiliency aided by the resiliency inherent in the members 33 and 34 which tends to cause these members to extend away from each other. This tendency in the members 33 and 34 of course results from the convergent arrangement of the neck arts 30 and the disposition of the blade c am s.

The clamp 36 is in the form of a band with an open side or in the form of a split ring, the ends of which are rounded in order to engage with reater facility the end portion of the handle and the device possesses greater resiliency than if the clasp was an uninterrupted collar.

In this case a magazine is made up by a separate strip 37 of metal riveted as indicated at 38 to one of the handle members and provided at its outer ends with flanges 39 and 40 extending up to the other member. The flanges confine the blades. This device is used precisely in the same way as that heretofore described except that to gain access to the magazine, the clasp 36 is pulled longitudinally off the handle and the two members of the device are then rotated upon the clamped post 11 until the blades may be removed or laced in the holder.

Fi ures 7 and 8 show a still further modified orm in which the two members 33 and 34 of the device are spread and rotatable upon the clamp postas just described and in this case a clasp 36 is used also. However, the magazine strip is done away with and replaced by pins 41 and 43 which are riveted to one of the membersand adapted to fit in perforations in the other member when the clasp is in place. The blades are fitted between the posts as indicated in Figure 7.

The jaws are slightly concave so as to grip the blades by. the edges of the jaws. The holder will take any type of blade and hold it at any angle.

The further purpose of the hole 17 is tohang the article upon a hook or other support when not in use.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications bein restricted only by the scope of the following claims.
